Step-by-step explanation:
<u>Parallelogram</u>
It's a quadrilateral formed by two pairs of parallel sides. The opposite sides have equal lengths.
We are given a parallelogram with opposite sides of 3x+1 and 6x-4. They must be equal, thus:
6x - 4 = 3x + 1
Subtracting 3x:
3x - 4 = 1
Adding 4:
3x = 5
Dividing by 3:

First you need to find the slope.
You do this by adding x to both sides to get 3y=x-12
Then, you divide by three on both sides to get y=1/3x -4
to find the new y intercept you insert the point and the slope in the equation
2=1/3(18)+b
You multiply 1/3 and 18 to get 2=6+b
Finally you subtract 6 on both sides to get -4=b.
This means that the equation of the line is the same as the given line
